good luck ... we have all been there:-)

Not sure I would have started with the locations though.

This topic comes up from time to time, so it might be worth searching both the

For Bison locations to work, your scanner will have to update the location 
structure.

I have implemented this for my PL/I scanner and parser.

look at the sourcecode at:
http://pl1gcc.cvs.sourceforge.net/viewvc/pl1gcc/gcc/gcc/pl1/


Search for the files:
pl1-scanner.l
pl1-parser.y

project home page:
